The results of an all-encompassing nurturing process will be a beautiful, healthy garden – your favorite place to spend Sunday mornings.
Although there are many types of weed killers available, we’d recommend using an organic option, since that’s the only way to get the best results and not harm the environment, the produce or yourself in the process.

Quick Navigation
What’s an Organic Weed Killer?
Organic weed killers or herbicides can break down more quickly without leaving any toxic residue.
They’re becoming increasingly popular because they’re eco-friendly and don’t harm people’s health and well-being. They’re not the cheapest option on the market, but are worth the investment due to the benefits they provide.
Organic herbicides are non-selective and cannot differentiate between the grass and other plants, and that’s why you need to be careful when applying.
What’s the Difference Between Organic & Chemical Weed Killers?
One of the primary differences between organic and chemical weed killers is the presence of the glyphosate ingredient.
Unlike chemical weed killers, the organic ones don’t contain this and are safer to be used for your vegetable and fruit produce, around your children, and animals. Plus, when using organic products, you don’t have to put your yard off limits – you can use it immediately.
Glyphosate works by building up and lingering in the soil for a prolonged period. If there is excessive exposure, the plants can undergo genetic mutations or, in worst-case scenarios, develop cancer.
On the other hand, organic weed killers function differently, and they don’t have an overwhelming smell that can overtake your lawn.
Most of the organic products are made with essential oils, and what’s more, they can even have a pleasant smell.
How Do Natural Weed Killers Work?
How organic herbicides work mainly depends on the type of active ingredients they’re made of. Most of the products we presented in our article are based on vinegar; however, they are other options, and you can check them out below:
Vinegar or acetic acid
The acid that’s present in the acetic acid is the same as in white vinegar; however, it’s much more concentrated. This means that they work in the same manner, but white vinegar needs more time to show the effects.
Moreover, these weed killers usually cause the leaves to turn brown in 24 hours. Younger plants can be treated with vinegar, and more established plants react better to the stronger acetic acid.
Furthermore, you may need to apply the vinegar weed killer more than once to achieve the best results and effectively remove weeds and grass from your porch or patio.
Saltwater or salt
Salt and saltwater kill grass in the same way as the ocean. The reason plants don’t grow in the sand is due to continuous saltwater erosion. It helps remove all the basic nutrients and moisture. This lack of nutrients is what kills the grass.
If you decide to use a salt-based organic product for weed removal, have in mind that over-application can cause damage and eliminate the grass from some areas, so you need to be careful when handling this product.
Saltwater and salt are ideal for use on paved areas, such as walkways, roads, and sidewalks, because they can be applied locally without causing damage to surrounding plants.
Eugonol
This compound is usually found in essential oils from cloves, which are commonly used in weed killer products.
It functions in the same way as acetic acid – it kills the leaves on the outside, leading to cell leakage and eventual death.
Although it effectively destroys the top parts of the weed, it’s not recommended for use on weeds with extensive root systems, such as tubers, rhizomes, and bulbs.
In any case, this type of product is effective in killing any grass on walkways and building edges, and it’s excellent for destroying young weeds.
Flame weeder
This is another option for burning the weeds in your yard. It’s propane-based, and it burns the weed.
However, this product must be used with utmost care, as it’s dangerous and may pose a fire hazard.
How Effective Are the Organic Weed Killers?
You might ask yourself whether organic weed killers are effective. Most of them require being sprayed on the plant, and their effectiveness depends on the type and size of grass you want to treat, as well as the weather conditions.
Most commonly, organic weed killers work well with weeds shorter than 4 inches, while perennial weeds need to be treated with more doses.
For optimal results, apply the product to young weeds on a dry, sunny day.
